VAPOR-BURNING APPARATUS.

SPECIFICATION formingpart of Letters Patent N o. 665,108, dated January1, 1901. Application led April 24, 1899. Serial No. 714,182. (No model.)

T0 all whom t may concern:

Beit known that I, ARTHUR KITSON,a subject of the Queen of GreatBritain, and a resident of Philadelphia, county of Philadelphia, Stateof Pennsylvania, have invented certain new and useful Improvements inVapor-Burning Apparatus, of which the following'is al specication.

My invention relates to vapor-burning apparatus, and is more specicallydesigned to produce an improved form of single-burner apparatus forburning the vapor of vkerosene 0r other iiuid hydrocarbon mixed with airunder the ordinary form of incandescent mantle.

The preferred form of my apparatus is'illustrated in the accompanyingsheet of drawings, in which- Figure 1 is an elevation and partialsection of my apparatus. Fig. 2 is a cross-section on line 2 2 ofFig. 1. Fig. 3 is a cross-section through the vaporizing-tube, showingthe internal filler therefor. Fig. iis a cross-section through theoil-supply tube and union, showing the wire-gauze diaphragm located atthe junction of the vaporizing-tube with its conmeeting-tubes.

Throughout the drawings like referenceflgures refer to like parts.

The lamp is preferably mounted on a reservoir or bowl (not shown)containing oil and compressed air, it being secured into said bowl bythe threaded nipple 1. A valve 2 controls the flow of oil from the bowlthrough the oil-supply tube 3 to the vaporizing-tube 4, which ispreferably made in the shape of a U or horseshoe, so as to extend upalongside of and across the top of the incandescent mantle 20, saidincandescent mantle being supported from the vaporizing-tube by the wire21 or other convenient means. 23 is a short chimney mounted on the upperportion of the vaporizingtube, and 22 is a drip-valve in the lower partof the b'urner apparatus. This burner and air-mixing apparatus are allmounted on or Within the upright tube 5. The vapor is carried from theend of the vaporizing-tube by the vapor-discharge tube 6 into the tube 5and discharged through the outwardlyflaring opening 7 into the upper endof the mixing-tube 8. This mixing-tube is of less diameter and lengththan the uppulling on the chain 11, connected to its outer ,Y

end.

' 12 represents the burner proper, which is formed by contracting theupper end of the main tube 5 or by inserting a thimble therein.

The gauze 13 is placed over the buruer-openn ing and held in place bythe annular cap 14. A second lower gauze 15 may be inserted in theburner. A metal collar 16 is placed on the upper end of the tube 5 andsurrounds the'burner 12, leaving an annular space between the two. Thiscollar, as shown, is in metallic contact with the tube 5, and theparticular construction shown might be varied, so long as anyconstruction was employed which gave free conduction of heat from thecollar 16 to the body of the tube 5.

.The U-shaped vaporizing-tube 4 is connected to the oil-supply tube 3and the vapordischarge tube 6, which are located on opposite sides ofthe burner, by means of the unions 17 17, and between the abutting endsof the tubes I preferably introduce gauze diaphragms 19 19, as shown. Inthe Vaporizing-tube is a U-shaped rod or wire 18, which is preferablysupport-ed in position by the wire-gauze diaphragme. l

`The method of operating my invention is as follows: The vaporizing-tube4 being heated by a' gasolene-torch or any other convenient means ofpreheating, (not shown,) the valve 2 is opened and the oil is forced upthrough the supply-pipev 3 and gauze diaphragm 19 'into thevaporizing-tube 4. As it passes up and over the mantle through thisvaporizing-tube it is compelled by the internal filler 18 to pass alongthe surface of the tube in a comparatively thin layer or film and isthus brought in thorough contact with the hot tube. By the time it hasapproached the union 17n it is in the form of vapor, which passesthrough the diaphragm 19, through the vapor-discharge tube G, and out atthe discharge-opening 7 in the form oi a jet- This jet passes down themixing-tube S, drawing in the necessary quant-ity of air through theair-conduits Sa Sb. The noise of the jet is partly muiiled andsuppressed by the muffler 9. The mixture of air and vapor passing out ofthe lower end of the mixing-tube S strikes the closed lower end of theupright tube 5 and is then compelled to change its direction and pass upthrough said tube 5 to the burner 12, where it is burned under themantle 20, giving off heat sufiicient to maintain the vaporizingtube 4;at the necessary temperature.

By pulling on the chain 11 the needle 10 can be projected up into theopening 7 when the same has become clogged by the accumulation ofcarbon, cleanses the opening, and

enables the lamp to continue in operation.

The radiated heat of the burner and mantle strikes the vertical portionsof the U-shapcd vaporizing-tube et, and the upward-owing current of hotgases is concentrated on the upper portion of the tube by the chimney23.

The advantages of my invention consist in its simple and compact formand in the fact that the mixing operation is all done Within the shorttube 5, which is kept hot by the fact of its metallic connection withthe burner 12 and the surrounding collar 16. The lower skirts of themantle 2O are of course kept hot by conduction from the upper portions,which are in the immediate vicinity of the Haine, and heat radiated fromthis lower skirt of the mantle is intercepted by the metallic collar 16.The oil-supply tube is also carried up through this upright tube 5 andbathed in the current of hot vapor and air within the same.

Itis evident, of course, that various changes could be made in thedetails of construction illustrated without departing from the spiritand scope of my invention so long as the relative arrangement of partsshown in the drawings or the principle of operation set out in thespecification is preserved.

The particular form, construction, and relation of, for example, theburner and mantle, the vapor-discharge opening, the needling device,dsc., herein shown and described are not specifically claimed, as thesame constitute the subject-matter of other applications now pending.

Having therefore described my invention, what I claim as new, and desireto protect by Letters Patent, is-
